Other major finds were at Cossack, Western Australia, and then further north when the Kimberleys goldrush began. The best finds were at Coolgardie and Kalgoorlie, which turned out to be the richest in Australian history, and this started the biggest and longest goldrush of all.
But the real rush westward did not start till 1887, when gold was found at Yilgarn and Southern Cross, east of Perth.
This brought miners like Arthur Bayley and William Ford into the region, who in 1892 found large deposits of gold at Coolgardie. In 1893, Patrick Hannan then found gold at Kalgoorlie, starting the biggest exodus from the eastern states to Western Australia ever.
Kalgoorlie eventually yielded 100,000 million pounds of gold and attracted diggers on a larger, more modern scale, like two Adelaide prospectors W. Brookman and S. Pierce. These two staked out hundreds of hectares and employed big teams to dig for gold in what became known as "the golden mile" - the biggest gold discoveries in Australia up to that time.
At its peak in 1903, Australia had become the world's largest producer of gold - half of which came from Western Australia. From that point on, the gold discoveries petered out, and the industry declined to a point where discoveries were minor and occasional. In the twentieth century gold is mined by large companies using modern technology.
